I'll have to trek down there and look for it. There's a Barnes and Noble on my way home from work - I'd stop there today but my wife is going to "Ladies night out," leaving me with my 19month old and 3 week old sons! (I forgot to tell everyone, we had another baby, on April 28th... after that time, I've been trying to whittle down on my incoming mail; I just broke the 2000 mark; hopefully, after this one starts sleeping through the night, I can become a little more active on the list again.) > > > > > So - at this point I'd like to ask the group: > > > > 1) Does anyone have OPTi's phone number, so I can call them > > directly. > > > > 2) Are other sound cards that have this phenomena, if so, > > what to people do about the printer wanting to use IRQ 7. > > > > Uh - oh!

Int 5 is > assigned to sio3 i believe... Yes, I had forgotten about simply moving the printer to IRQ 5 - but, as you say, I'll have to regen a kernel just to get it. I'm used to that, since I have my NE2000 sitting at IRQ 9 instead of the default. > > I sort of have it all sorted out on my machine , but it really > just takes a lot of annoying fiddling to get it all to fly.
